BRICK-MACHINE.

Specification forming part of Letters Patent No. 43,162, dated June 14,1864. Y

To all whom it may concern.'

Be it known that we, PORTER L. SWORD, of Adrian, in the county ofLenawee and State of Michigan, and GEORGE S. TIFFANY, of the samecounty, have invented a new and Improved Brick-Machine;` and we dohereby.

declare that the following is a full and exact description, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

The object of this invention is to produce a machine that will work muchstiffer clay than is generally used in brick-machines, and make brickthat may be put in the hake7 directly from the machine.

To enable those skilled in the art to make and use our invention, wewillproceed to describe its construction and operation.

Figure 1 is a side elevation of our invention. Fig. 2 is a detached viewof a part of the frame. Fig. 3 is a central vertical section of ourinvention, excepting the shafts and the bea-ters of the grinding-mill,which are shown in elevation in full. Fig. 4 is a plan of the partsbelow the mold-wheel. Fig. 5 is a part of vertical section taken throughtheline m u, Fig. 6. Fig. 6 is a horizontal section taken through theline a' y, Fig. 1.

Like letters indicate like parts in all the figures. The parts coloredblue are those which may be made of iron, that are cut by the plane.

The machine may rest upon four pedestals, m m m' m.

The Ashaped castings B B, bridge-tree A, and bed-plate I constitute theframe ot' the machine.

The grinding-mill consists of cylinder S, bolted to the bed-plate, andshaft D, having beaters spirally arranged thereon. Motion may be givento the shaft D by means of a sweep in the box H, when the machine isdriveniby horses, or, if steam is used, by suita` ble gearing attachedto said shaft. The 1noldwheel K is attached to the lower end of theshaft O, to which motion is communicated from the shaft D through thecog-wheels F G. The bottoms of the molds have pins E E, Sto., attachedthereto, which, as the mold-wheel rotates, traverse the circularinclined plane R, by means of which the bottoms of the molds are raisedto the surface of the wheel, forcing the molded bi-ickfrom the mold. Themoldwheel K has a ange from its face or periphery, and is supported bythis flange resting upon three wheels, P P P, and` by a step in thepedestal Z for the shaft O. The shafts of the wheels P P P radiate frompoints below the center, and have bearings in the pedestal Z. Theirouter extremities are supported by rods a a a from the bed-plate, and:may be raised or lowered by means of nuts on the rods above thebed-plate. The object of these wheels is to support the mold-wheel underthe `pressure brought upon it in filling the molds and to keep the wheelnear to the bed-plate. Two segments, o o, are bolted to the under sideof the bed-plate in such a position as to cover the space between themold-wheel and the bed-plate and prevent the exuding of clay therefrom.Their position and plan are shown by the broken lines in Fig. 6. Thereis an elevated portion of the bed-plate J, which forms a recess from theunder side of 4the bedplate that communicates with the grinding-mill.Within this recess W an inclined plane, o, having curved sides, ispivoted, the lower end of which rests upon the side of the wheel and isfixed in that position by means of the screw L, which works in a threadin the elevated portion of the bed-plate J. The sides of this recess Wform continuous curves with sides of an opening in the bed-plateextending across that part which forms the bottom of `the cylinder S,described from the center of the shaft O. This opening is over the spacetraversed by the molds. Below the moldwheel, and directly beneath theinclined plane, is a wheel, T, so placed that when the moldwheelis inmot-ion the pins in the bottoms of the molds pass over it and are raiseda very little, thus producing a pressure upon the clay in the mold frombelow at the same time that it is subjected to a pressure from above bythe inclined plane o. This insures the filling of the lower corners ofthe mold and accomplishes it with much less power thanit would requiresimply with the beaters and inclined plane o. The shaft of the wheel Thas a bearing in thevpedestal Z, and its other extremity is supportedand adjusted vertically by means of a rod from the bed-plate and a nut.

The operation of this machine is as follows Motion is given to thegrinding-mill shaft from left to right, causing the mold-wheel K torevolve in the direction indicated. Moistened clay is 4thrown into thecylinder S, where it is thoroughly ground and forced through the openingin the bed-plateinto the molds and into the recess W by the beaters. Thepin E in the bottom of the mold leaves the circular inclined plane asthe mold passes beneath the grinding-mill S. From the time the moldiirst comes beneath the, grindingmill until it passes under the inclinedplane o it is being iilled by the pressure produced by the beaters onthe grindingmill shaft D. Then passing under the inclined plane 0 theclay in the mold is subjected to a pressure from below, as beforestated, by means of the wheel T and pins E. After passing the wheel T,the bottom ofthe mold descends and the filling is completed by theinclined plane o. The mold then passes under the scraper u, whichremoves all surplus clay, after which the pin E strikes the circularinclined plane lt, by means of which the bottom of the mold is graduallyraised to the surface of the wheel, i'orcin g the brick from the mold,when it is rem )ved by hand. The bottom of the mold then descends as thepin E descends the inclined plane It, and the mold is refilled in theSame 111211111161'.

It will be seen that the mold is being iilled from the time it passesbeneath the grindingmill until it leaves the inclined plane o-aboutone-third of its revolution--and is powerfully compressed by theinclined plane o and wheel T; consequently very stilil clay may be used,and the brick are'put in the hake directly from the machine.

We claim nothing new in the mold-wheel K nor in the arrangement of themold-wheel inclined plane R and grinding-mill.

What we claim as new, and desire to secure by Letters Patent, is-

l. Constructing the bed-plate l with the recess W, and curvilinearopening in that part which forms the bottom of the cylinder S, over thespace traversed by the molds, in combination with thevinclined plane oand wheel T, when they are arranged to operate substantially as and forthe purpose herein set forth.

2. Supporting and adjusting in proximity to the bed-plate the mold-wheelK by means of the wheels P P P and rods a a a, as set forth.
